【摘要】 <正>我们于1976～1977年对广东省中山县鼻咽癌、鼻咽粘膜病变患者及健康人头发中微量元素含量进行了比较,初步发现男性鼻咽癌病人头发中镍的含量偏高,钼的含量偏低,而女性鼻咽癌病人头发中镍的含量却偏低,与男性不一致。为了进一步研究微量元素与鼻咽癌发病的关系,于1980年在鼻咽癌高发区的四会县(1970～1979年年平均死亡率16.07/10万人口)及低发区五华县(1970～1972年年平均死亡率1.67/10万人口)收集鼻咽癌病人及健康人头发进行微量元素含量的测定,现将结果报告如下。更多还原

【Abstract】 In 1976-1977, we found that the nickel contents in hair of male nasopharyngeal carcinoma (NPC) patients were higher than that of male normal persons, but the molyb-denun contents in hair were lower.In order to elucidate the correlation of trace element contents in hair of NPC patients with the etiology of NPC, 83 samples of hair of NPC patients and 137 samples of hair of normal persons from the NPC high risk area (Sihuj County) and the low risk area of NPC (Wuhua County) were collected in 1979-80 years and the contents of trace elements (Ni, Cr, Cd, Cu, Zn, Mo, Pb, Mn, Ba) in these samples were analyzed by emission spectrum technique.The results showed that the nickel and chromium contents in hair of NPC patients(average: Ni 3.60μg/g. Cr 0.51μg/g) were higher than that of normal individuals (Ni 2.18μg/g, Cr 0.24μg/g), but themolybdenum contents in hair of NPC patients (Mo 0.09μg/g) were lower than that of normal individuals (Mo 0.17μg/g), The differences were all significant statistically.The results of two investigation for the determination of trace elements in hair of normal and NPC males were rather similar.In comparing the trace element contents in hair of NPC patients and normal individuals, it was suggested that there may be some association of the contents of nickel or molybdenum in hair of NPC patients with the etiology of NPC更多还原
